Anthony,
I was on the phone with him for over 2 hours. We talked about everything from how to grow the right flax for canvas the best kind of oils used for paint making, cold-pressed, refined, you name it.
I took notes but the amount of information he has was overwhelming. He has a site and you can email him. It is better it comes directly from him than second hand from me.
After scouring the universe for the right kind of oil paint for my use, I came across his paint and won't use anything else.
